ABSTRACT:
A method reads out X-ray information stored in a storage phosphor layer where an X-ray picture is obtained and made up from a number of pixels. The method includes the steps of: irradiating the storage phosphor layer with a stimulation light beam which is moved along a line over the storage phosphor layer to stimulate the storage phosphor layer into emitting emission light; collecting emission light emitted from the storage phosphor layer, and converting the emission light collected into a corresponding detector signal S; deducing a number of detector signal values D from the detector signal S, where the number of deduced detector signal values D is greater then a predetermined number of pixels of the X-ray picture along the line; and deducing a picture signal value B for each pixel of the X-ray picture along the line from at least two of the detector signal values D.
